ACCOUN'IINGr-MACHINE-CONTROL MEAN S.

Specification of Letters Patent.

Patented Nov. 2, 1920.

Application filed March 16, 1918. Serial No. 222,885.

To all whom it may concern Be it known that 1, JOHN F. Roma, a citi- Zenof the United States, residing at Nashington, in the District ofColumbia, have invented certain new and useful Improvements inAccounting Machine Control Means, of which the following is aspecification.

The improvements of this invention have to do primarily with accountingmachines, andinvolve certain provisions for effecting abnormaloperations of such machines from the handle of the actuator by which anaccounting machine is ordinarily operated. More specifically speaking,accounting machines are commonly of two types,-manually operated andmotor operated, the first type being operated by a handle applied to acrank part, while the second type is operated by a handle, usually knownas a clutch bar, adapted to cause operation of the machine by thedriving motor.

By normal and abnormal operations of the machine as referred to above, Ihave in mind say in the case of an adding machine the use of the machinenormally to set up and add accounting items; and the use of the machineabnormally in the sense of performing total, sub-total, correction,repeat- The last mentioned actions of the machine are special actions,so to speak, as distinguished from the regular normal use of themachine.

My present invention embodies provisions directly associated with thehandle member or clutclr bar of motor driven type ac-' counting machinesby which the control means for effecting the abnormal operations of themachine are centralized at or upon the clutch bar handle for operationincident to the action of the latter in performing its function.

Another feature of the invention resides in a special provision wherebythe clutch bar handle of motor driven type accounting machines is causedto be actuated with extreme ease by means which in effect results inoperation of such part by combined manual and motor actuation.

Subsidiary to the foregoing, my invention resides, in respect to bothphases of construction and. operation above set forth, in theutilization of peculiar electrical connections and functioning of parts.

These and such other objects as may hereinafter appear are attained bythe novel construction, combination and arrangement of parts to behereinafter specifically described and claimed. Reference will now behad to r the accompanying drawings forming a part of this specification,wherein:

My invention is shOWn as applied to a motor driven type of adding oraccounting ma chine known as the, International adding machine. Thismachine not includingthe motor driving features, bein fully disclosed inUnited States patent of W ite No. 1,192,721, issued July 25, 1916, willnot therefore be described in detail. It sufiices to state also that themotor driving features shown in association with the improvements hereofmay be conventional, including the usual motor A with which may beconnected any suitable source of electric current, said motor beingcarried by a casing B in which are rec verging levers 6, seen in Fig. 1and other 110 parts associated with the shaft 2 are such as used in thetype of adding machine referred.

to connect the motor A operatively to above and their action, being wellknown, is not set forth in detail.

.in the manner previously uggested whereby the shaft 2 will be actuatedto cause an operation of the mechanism of the accounting machine in thewell known manner. The clutch bar handle C shown herein is of specialconstruction forming a feature of the invention and will shortly be setforth.

As a part of the keyboard mechanism of the machine ll utilize a totalslide 9, a subtotal slide 10, a correction or error slide 11, and arepeat slide 12, these slides corresponding with the total, sub-total,correction or error and repeat keys of the adding machine of the LettersPatent before identitied. The said slides, furthermore, functionsubstantially the same as do the corresponding keys mentioned, in orderto control the various abnormal or special operations of .the accountingmachine, indicated by. the

names which it have applied to these slides. Since the manner in whichthe slides are operable to effect the stated abnormal operations is setforth in the said Letters Patent, it may be presumed to be conventionaland known to those versed in the art and there fore requires no furtherdescription.

The several slides 9, 10, 11 and 12 are formed with extensions 9', 10,11 and 12',- respectively, at their lower ends, these extensions" beingso formed at the lower extremities as to provide the core pieces ofsolenoids 13, one of which is provided for each slide. The severalsolenoids are mounted on the base of the adding machine and are suitablyincluded in the electric circuit shown best diagrammatically in Fig. 3.

Referring particularly to Figs. 2 to 8 in-' clusive, the mannerin whichI have centralized at and upon the clutch bar handle 0. the variousspecial or abnormal action keys or control members will be apparent. Inthe relative arrangement of these last mentioned parts I have had inmind that the depression of the clutch bar handle G is ordinarilyelfected by a lateral rearward movement of the right hand of theoperator of the machine; that it is advantageous to reduce to theextreme minimum all move ments of the hand of the operator for effectingboth normal and abnormal operations of the accounting machine; that ifthe usual lateral movement of the operators hand for depression of theclutch bar handle may be employed to also operate the special keys orcontrol members of the accounting machine, increased efiiciency of theoperator must result; and that a centralizing of said special issueskeys or control members upon the clutch bar handle is the mostconvenient and ready construction whereby to obtain the increasedefiiciency of action stated. I

With the above in View, therefore, while my clutch bar handle C ismounted practically after a manner somewhat common in the art, that isloosely supported for ready and easy depression, said handle has beenspecially constructed so that it not only constitutes a clutch bar but abase carrying an assemblage of special or abnormal action control keysor members.

These members as illustrated comprise repeat, error, sub-total and totalkeys or finger pieces, respectively numbered 14:, 1'5, 16 and 17, seeFig. 3. The keys or finger pieces 14:, 16 and 17 being of likeconstruction one only need be described in detail; the key 15 functionsin a somewhat difi'erent manner.

A pintle rod 18 extends nearly the length of the handle C and theseveral keys or control members are pivoted thereto. Each member ispreferably made of an insulation substance, as is the handle C, andcarries a pivot plate 19 formed with ears 19 and 19 through which therod 18 passes. The ear 19 is downwardly elongated and bent to form aterminal contact 19. An insulation block 20 is secured to the ear 19 asshown. A spring 21 normally holds the key at the upper limit of itsmovement (see Figs. 6 and 7). Beneath each key member 14,16 and 17, is ayieldable contact 22 which is a piston-like part, the lower head 22 ofwhich 'is mounted in a casing 23 and upheld by a spring 24 from whichleads'ofi an electric circuit wire 25, the securing means of the casingforming a sort of binding post. The parts beneath the key member 15 arelike those just described except the contact 22 is rigid ornon-yielding, for reasons to be made clear hereinafter.

Formed in the under side of the handle C above each contact 22 and 22 isa recess 28 adapted to receive the opposite contact under certainconditions when the handle C is depressed. As seen in Fig. 2, the handleC has a middle contact 26 normally engaging a yielding contact 27, andin conductive engagement with the pintle 18 which forms does not takeplace until the handle practically reaches the lower limit of its move-'ment, (see dotted lines of Fig. 7,) whereas the parts 19 and 22 or 22establish closed circuit connections during initial movement of saidbar, if previously actuated for such urpose.

With the foregoing in mind, if the operator is adding on the accountingmachine by normal setting up and accumulation of regular items, theordinary mode of operation is employed, namely depression of properamount keys, and the lateral throw of the hand to hit and depress thehandle C. In such action the hand should engage the middle portion ofthe handle C, which at such portion is inclined and free of keyelements, as seen at c, Fig. 4:. If a totaling (an abnormal) action isdesired, the hand action will vary slightly to the extent that the handwill engage the key member 17 for depressing the handle C. This causesinitial depressing of the key member working pivotally on the pintle rod18, before moving the handle C. The contact 19 of the member 17 is thusinstantly moved above its coacting contact 22 and thereafter the parts17 and C move down together, whereupon the contact 19 engages the part17 and closes the circuit through the solenoid 13 which operates thetotal control slide 9. The total-taking devices are thus pre-set afterthe known manner, and the handle C continuing downward in its movementafterward clutches the motor A to the shaft 2 and operation of theaccounting machine to take a total and clear the accumulatorresults.

On such movement of the handle C the other contacts 22 and 22* areinactive because they enter the recesses 28,and there is no liability ofthe adjacent contacts 19 functioning because their insulation blocks 20intervene between them and the. contacts 22 or 22 as the case may be.

The operation of the sub-total and repeat key members 16 and 14,respectively, is substantially like that above described, since theseparts to cause functioning of the special parts controlled thereby mustbe preset, and the pre-setting action must be accompanied by anoperation of the main shaft 2.

The utility of the correction or error key member 15, however, involvespre-setting, but not an accompanying operation of the main shaft 2. Thatis to say, the correcting of a key-board simply means restoration ofaninadvertently depressed amount key or keys so that the action that wouldbe predetermined thereby is prevented, allowing a resetting of theamount ke-s, actuation of which is really required. or this reason themotion of the hand that is to control action of the error key member 15,see Fig. 5, is caused to depress said key member so that its contact 19is over the adjacent contion to the tact-22*, and is caused to engagethe latter by the very slightest depression of the handle or clutch barC. Being non-yielding the art 22 prevents that degree of movement of thehandle C necessary to cause it to perform its clutch operating function.

It will thus be seen that by my invention an operator of an accountingmachine is able to eliminate entirely. at least one special movement ofhis hand for causing abnormal operations of the machine in the sense ofsuch operations as herein set forth. Furthermore, he is enabled toemploy what is a necessary, and therefore a quite natural and easy, handmovement by which to control the abnormal functioning, all with theresult of saving of effort and increase ofefiiciency. The fact that inthe motor driven type of accounting machines there are always presentsuitable provisions for the supply of electric current for the motormakes the adaptation of this invention to such machines especially easy,involving primarily the extension of circuit wire connections to includethe operating electrical devices of the invention.

It is contemplated that the springs 24: coacting with the contacts 22and 22 shall be very light, but they necessarily must present someresistance to the pressure required to actuate the handle C, which isadditionally acted upon by an uplifting or restoring spring not shown.With a view to rendering the handle C yieldable to a very light touch,there is provided for the drag bar 1 an actuating solenoid 30 includedin a circuit comprising wires 31 (see Fig. 3) leading to the source ofelectric current E. Normally this circuit is open owing to the provisionon the under side of the part C of a special switch including thestationary contact 32 and the sliding contact 33 spring-pressed toengage contact 31. The contact 31 is normally spaced from ayielding-contact 32 which is similar to contacts 22 above described.

The pull of the solenoid 30 is downward relatively to the drag bar 1 toexert a corresponding force in such direction in relahandle or clutchbar C. Preferably the force of the electro-magnet is insufficient ofitself to move the part C down, being primarily intended to besufficient, however, to almost counteract the resisting force of thesprings 24 and the restoring .means forthe handle 0, which latter mustoverbalancethat of the solenoid 30 in order that the restoring actionmay take place.

The function of the parts just set forth will be understood when it isnoted that the touch of the operators hand upon any one of the keymembers 14:, 16 and 17 of the handle C will initially actuate such keymember as described, close the operating circuit for the control slideof such key memher on the subsequent slight initial downward movement ofthepart C. Thereupon after, the slightest additional downward movementof the handle C the contacts 32 and 32 come together, closing thecircuit of the wires 31 and solenoid 30, thereby energizing saidsolenoid 30 and causing it to exert its downward pull on the handlewhich practically but not wholly neutralizes the resistance of thespring contact 22 and the handle restoring means. As the handle C aboutreaches its lower limit of movemenp a cam 34 engages a projection 33' onthe contact 32, slides said contact 32 laterally to disengage it fromthe contact 32 and thus breaks the circuit of the solenoid 30.deenergizing the latter. This action permits a quick return of thehandle C to its normal uppermost position uninfluenced by the downwardpull of the solenoid 30 and when said handle resumes its normal positionthe solenoid 30 is inefiective owing to the spaced relation of thecontacts 32 and 34:-

My invention comprehends the use of the principle of action of thesolenoid 3021s a supplement to the features of the inventionfirst-described, or the parts 30 to 3 inclusive may be entirelydispensed with as they are not necessary for the efhcient embodiment ofthe construction of the handle clutch bar C afiording the centralizedkey member control.

Again, the principle of actionv of the solenoid 30 may be utilized aloneas an electrical appliance for actuating a clutch bar handle requiringthe mere closing of an electric circuit to relieve the hand of .anoperator of the work entailed in fully depressing a clutch bar such asusually employed on motor driven accounting machines.

The term abnormal as used herein contemplates, furthermore, anoperationof an amounting machine and some machine or mechanismrepresenting an independent operating unit which might be associated or.worked with the accounting machine, under which conditions the normaloperation would be that of the accounting machine alone and the abnormalaction the working of the accounting mechanism with the associated unitmechanism. Such a machine is disclosed in U S. Patent of Serum andBrockman, No. 1,257,143 issued February 19, 191e,

It is also to be understood that while I prefer the arrangement of thekey members on the handle (1 such that they act as circuit closers onslight depression of the handle, it is quite within the purview of myinvention that they may close their controlled circuits by their initialmovement relatively to the handle. Under these, conditions thepre-selection actuations incident to abnormal operations of the, machinetake place prior to depression of the handle C.
